SPECIFICATIONforming part of Letters Patent No. 264,925, dated September 26, 1882.

Application filed February 15, 1882. (No model.) 7

To all whom it may concern:

Be it known that we, EDWIN RHGAHOONE and CHARLES E. OAHOONE, of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Bridle-Bits; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference which similar letters of reference indicatelike parts in each of the several figures, Figure 1 is a sectional view of a portion of a bridle-bit, clearly illustrating our method of combining the cheek-piece with the head of themouthpiece; Fig. 2, a cheek-piece detached from the mouth-piece Fig. 3, an end view of a head hollowed out to receive a mouthpiece-core covering, and illustrating two methods of keying the core within the head. Fig.4 shows a head provided with a projecting shank adapted to cause the core-covering to flare. Fig. 5 illustrates a detail of the head. Figs. 6, 7, 8,9, and 10 illustrate our improved method of constructing a mouth-piece; and Fig. 11 illustrates our head and mouth-piece with further improvements, which will be described. Fig. 7 is a section taken through line as; and Fig. 8, a section of an open jacket, taken through line y.

In carrying out our invention we cast or otherwise form the cheek-piece a with buttons or bulbs g on that portion thereof where said cheek-piece engages with the mouth-piece head, asshown more clearly in Fig. 2, said bulbs having recesses g formed behind them. The

cheek-piece is then, or may be, laid in molds and the head I) cast around the said buttons or joints between the head and cheek'piece, as will be clearly understood.

Within the head b, and between the bill bed extremities of the cheek-piece, we form a socket for the reception of the mouth-piece or core d, which said socket may have a female screwthread formed therein adapted to engage with a male thread on the shank, or any other manner of uniting the two parts may be carried into effect, although the method described is preferable, it giving greater security to the parts.

The threaded extremity of the shank may be keyed into the socket by means of the 1011- gitudinal key 6, or by means of a pin, e, passed through the side of the head, as shown in Fig. 3. i

We form, or may form, within the head I) a recess, f, adapted to receive the end of the core-coverin g a. one integral piece to form a rigid mouth-piece, or the same may be jointed and form a flexible mouthpiece.

Should we desire, we may form a flange, h, (shown in Figs. 4 and 11,) projecting from the head 1) around the core 01. It is thus adapted to cause the extremities of the tubular coverin g to flare and form a more perfect protection against the metallic portions of the bit from The end of said flange it may engage with a shoulder, g, on and surrounding the mouthpiece core, and the flaringportion of the mouth piece be thus lengthened, as shown in Fig. 11. The said flaring portion, in addition to the purpose above stated, serves to prevent the horse from getting a strong purchase with his said teeth being on a horizontal line and the bit at an angle thereto, the surfaces of contact are greatly reduced, as will be apparent.

Although we do not limit ourselves to it,

ness, to construct our mouth-piece as follows:

A link, 0, preferably of wire, and of brass or other similar non-corrosive composition, connects the shanks d, (or any sections of the mouthpiece.) the wire being simply bent, as

teeth upon the bit. Thebearing-surtace of the.

we prefer, because of its simplicity and cheap bulbs, forming in a certain degree dovetailed shown more clearly in Fig. 10. The said brass portion of the mouth-piece will notbe affected to any detrimental extent by oxidation or other decomposition caused by thejuices and saliva from the horses mouth; nor will the brass be weakened by contact with the rubber covering, which contains sulphur, all of which defects are common to any iron mouth-pieces.

Over the link or links 0 we form a metallic binding-jacket, 19, adapted to prevent the link from uncoupling and to give solidity and rotundity to the mouth-piece. Said jacket has longitudinal projections 1, adapted to pass between the wires, so that when said jacket is bent to protect the Wires the latter are in closed in separate chambers, as will be clearly understood upon reference to Fig. 7. Each end of the jacket may have notches 8 formed in them to give a closer joint with the sections. By means of the screw-core d, adjusted within the head I), the distance between the cheek-pieces of the bit may be increased or diminished at pleasure to adapt thesaid bit to the width of thehorsesmouth. Thisactionisaccomplished by simply removing the longitudinal key. 6, screwing up or unscrewing the core and reinserting the key, as will be understood.

A recess, a, may be formed to allow a pair of nippers to catch the end of the key, which should not, as will be evident, interfere with the covering a.

In thus describing an extensible mouth-piece we do not wish to be understood as limiting ourselves to the exact arrangement herein shown, but wish to be understood as claiming the feature broadly, as set forth in the claims.

What we claim is,

1. In combination, in a bit, a mouth-piece core having threaded extremities, socketed heads adapted to receive said mouthpiece core, and keys adapted to hold said heads and said mouth-piece in fixed relation to one another, as set forth.

2. In a bit, the bulbed or dovetailed extremities g ofthe cheek-piece working in sockets in the head of the mouth-piece, substantially as set forth and shown.

3. In combination, in a bit, a cheek-piece having bulbed extremities, a head having corresponding recesses therein,andhavingasocket between said recesses adapted to receive the mouth-piece, and a mouth-piece, said parts being arranged and operating substantially as and for the purposes herein set forth.

4. In a bit, the cheek-piece having the pivotal parts g dovetailed within a head, said head having a threaded socket adapted to receive a threaded mouth-piece, substantially as and for the purposes herein set forth.

5. In a bit, the combination, with the core at and covering 0, of a head having a projecting flange, h, adapted to cause the extremities of the covering 0 to expand, substantially as and for the purposes herein set forth and shown.

6. A bit having therein a mouth-piece'composed of sections connected by a link, 0, covered with a metallic jacket, 79, substantially as and for the purposes set forth and shown.

7. In combination with the link 0 ofa bridlebit mouth-piece, ajacket having longitudinal projecting ribs 1' adapted to pass between the sides of the link, said jacket being adapted to prevent the said link from uncoupling.

8. In a bit, acheek-piece havingbulbs 9 thereon, a head having corresponding recesses, and

havingthe flangefprojecting therefrom, a core,

d, secured in said head, and a covering, 0, all arranged in combination, substantially as and for the purposes set forth.

9. In a bit, the head provided with the flange h, causing the mouth-piece covering to flare, substantially as and for the purposes set forth and shown.

10. In abit, the head provided with theflange, in combination with the core provided with the shoulders q, substantially as and for the purposes set forth and shown.

11. As an improved article of manufacture, a bit having a head carrying bullied cheekpieces, said head having a threaded recess therein to receive the mouth-piece core, having recess f to receive the end of the covering 0, and having a flange,-h, to cause said covering to flare, a mouth-piece having therein a link,

0, coupling-sections, as d, a jacket, 19, covering and binding said link, and a covering, 0, the whole being arranged and combined substantially as and for the purposes set forth and shown.

In testimony that we claim the foregoing we have hereunto set our hands this 31st dayvof January, 1882.
